3G Network - Analysis & Simulation

End-to-End Voice, Video and Data Quality Testing

Using GL’s VQuad™ with the Dual UTA HD, or all-in-one VQuad™ Probe, along with centralized analytical tools, voice, data, as well as video quality can be tested simultaneously on a wireless or wired network.

Since the GL’s VQuad™ solution is network independent, all Voice and Data networks are supported including 3G, WiMax, 4G LTE, Advanced LTE and the upcoming 5G. And since the GL VQuad™ solution supports both Narrowband and Wideband traffic, VoLTE testing is fully supported.

GL’s VQuad™ NetTestsolution provides automated data testing on Mobile Devices (Android and Apple) as well as PC based internet connections. The Data Testing includes TCP, UDP, HTTP, FTP, DNS, VoIP, SMS, and Email tests. GL’s Video Application Part (VAC) supports Video Conference testing between any two VAC Agents. GL’s VAC Agents can be installed on any Android device, Win PCs or Linux box. GL’s Voice Quality Testing (VQT) supports automated voice quality between any two nodes within the network using latest ITU based algorithms including Perceptual Objective Listening Quality - POLQA (ITU-P.863) and PESQ (ITU-P.862). The POLQA algorithm is specifically used for testing Wideband voice over networks.

• Complete end to end voice, data, video quality testing of LTE network-visit Automated Network Wide Testing
• Automated test statistics and results across next generation LTE network can be accessed via web interface
• Connect to Mobile Phones, Smart Phones, and Broadband Devices using GL’s portable VQuad™-Dual UTA HD system
• Test LTE devices for Voice, Data, Video quality metrics with complete automation and centrally controlled system
• Use GL’s VQuad™-Dual UTA HD to confirm quality of service during the network upgrade process
• VQuad™ can remotely perform Automated Data Testing on any Android or IOS mobile devices (running the GL NetTest app), irrespective of where the phone is located, and whether the phone is on a voice call or not.
• Perform automated data testing on PC-based Broadband Internet (Broadband 3G/4G/LTE, WiFi, Wired) and on Apple/Android Mobile Devices - tests include TCP, UDP, HTTP, VoIP, FTP, DNS, SMS, UEInfo, SimInfo, and PhoneInfo
• Supported devices - Mobile Radio (PTT) & Mobile Phones (VoLTE, 4G, 3G, Wi-Fi, WiMax)
• Supports both Narrowband (8k sampling rate) as well as Wideband (16k sampling rate) connections for use in VoLTE networks utilizing the AMR-WB codec

As an example, the screenshot below illustrates the HD voice quality measurement of calls using POLQA-

• VQT software includes industry standard voice quality analysis algorithms - POLQA and PESQ
• POLQA testing is available for VQuad™ interfaces
• VQT can be configured for fully Automated analysis of recorded voice files
• Full Reference algorithm (FR) measurements with high accuracy for dedicated tests in live networks
• POLQA analysis results include POLQA MOS, E-Model, Signal Level, Noise Level, and Jitter
• Real-time mapping of results with GPS option used in conjunction with VQuad™. Results mapped in WebViewer™ using Google Maps
• The results can be accessed remotely from a database using the WebViewer™, displayed in both tabular and graphic formats

Monitoring

Functionalities

• Wireless Network Monitoring and Surveillance System (passive / non-intrusive) –UMTS, GPRS
• Ability to identify and analyze CDR using Key Performance Indicators (KPI’s)
• Ability to listen to the Voice calls
• Set alarm conditions and generate alerts of different types like email alert, visual alert, audible alert, or even log into tables for future analysis
• Reports are displayed both in tabular and graphical formats; customize reports and graphs based on SQL queries
• Graphs provided for Call Completion Ratio, Answer Call, Listening MOS, Conversational MOS, Failure Cause, and Call Duration
• Real-time data displays information such as called number, calling number, source & destination IP address, RTP packet details, call flow graph, frame decodes and more
• Apply single or multiple filters for data analysis; use logical operators between filters
• Ability to export the call detail records displayed based on time filter or record index as PDF and CSV

Typical Applications

• Comprehensive analysis from overall network health to detailed protocol monitoring
• Call Detail Records, fraud detection and location, remote protocol analysis and troubleshooting, real-time signaling monitor, traffic optimization engineering, and statistics.
• Determine actual call signaling routes to verify network functionality under all situations
• Revenue and billing verification, alarm monitoring, intrusive testing.
• Quality of service measurements call trace and recording.

KPIs
